Hello,.
My plant has 2 gas turbines with a single-shaft one on one configuration with the same machine. I have a problem with No.1 gas turbine combined cycle load can't reach base load. I noticed the compressor discharge temp of gas turbine No.1 was limited by 510 deg-C and IGV position lower than No.2 gas turbine.
first I need to know the purpose of CTD limit control.
second, why does No.1 not increase IGV position for reach base load.
Ps. No.2 gas turbine IGV position open more than No.1 gas turbine.
Thanks.
